Hi,
This problem is caused by FAT file format. The solution to this error is to convert the file format to NTFS.
Click the Start button
Click All Programs
Click Accessories
Right click Command Prompt
Click Run as Administrator
Enter the command, convert /fs:ntfs /nosecurity (drive should be the drive letter of your external hard drive, for example convert F: /fs:ntfs /nosecurity )
Hope above information can help you.
